The invention relates to a method and a system for producing a foundation element in the ground by means of a construction apparatus, wherein by means of a ground working tool a hole is formed in the ground, in which the foundation element is produced, wherein by means of a control and evaluation unit at least one operating variable of the construction apparatus, which changes depending on a ground composition, is detected as a function of a working depth. According to the invention provision is made in that in the control and evaluation unit a ground profile to be expected is entered, which indicates a layer structure of the ground with ground layers of different ground composition, and in that by the control and evaluation unit the detected, at least one operating variable is set in correlation with the stated ground profile in order to establish, at which working depth a transition between ground layers of different ground composition is present.

Disclosed herein is a system and method for determining the compaction of terrain based on rolling resistance. The system comprises a work machine configured to move along a route along the terrain, a navigation system configured to generate route data indicative of the route, a sensor configured to generate operating parameter data indicative of an operating parameter of the work machine moving along the route, and a processing unit. The processing unit is configured to process the operating parameter data to generate rolling resistance data indicative of the resistance by the terrain to the movement of the work machine along the route, and to process the rolling resistance data to generate compaction data indicative of the compaction of the terrain along the route.

An underground sampling tool (HTMS) for underground water analysis of both quality and flow rate, providing the information required to perform an underground drilling and obtain uncontaminated water for crop irrigation, said tool comprising: a housing for the electronic and electrical controls, a housing for the hydraulic means controlled by the electric and electronic portion of the tool, a test body consisting of a variety of hydraulic circuits for operating the various operating valves of the tool, wherein said test body further comprises: a rear shoe on an axial axis of the tool, wherein said rear shoe is driven by two telescoping pistons simultaneously that arise from the inside of the tool when driven by a signal of a surface equipment operably enabled for this purpose, and a front shoe, driven by several pistons which are housed below the front shoe, not shown in the figures, and driven by one or more electro-pneumatic devices acting jointly and generating a progressive forward or backward movement of the front shoe. Process for the collection and analysis of samples in a wellbore using said tool.

Embodiments describe a method for moisturizing soil at an open construction site. The method includes determining a target soil moisture level for the soil at the open construction site; measuring a current soil moisture level of a location within the open construction site with a moisture sensor while the moisture control system is moving along a predetermined path across the site; storing the current soil moisture level of the location in memory; determining a target volume of water for achieving the target soil moisture level at the location based on the current soil moisture level at the location; calculating a target application rate to achieve the target soil moisture level at the location based on the target volume of water; and applying the target volume of water at the target application rate to the location when the system is positioned to dispense water at the location of the site.

A work machine with a chassis, a wheel hub rotationally coupled to the chassis, a tire coupled to the wheel hub and configured to engage an underlying surface, and a controller communicating with a plurality of sensors and having a memory unit. Wherein, the controller stores tire data for the tire in the memory unit and the controller determines a cone index of the underlying surface of the work machine based on the tire data and the plurality of sensors.

The disclosure relates to a method for compacting a soil, wherein:

a) a ramming cycle is carried out several times on an impact area of the soil during which: a mass (16) is dropped on the impact area from a predetermined height (A); and after the impact of the mass (16) on the impact area, a point cloud is acquired using a laser scanner in order to obtain a radar image of at least the footprint (E) of the mass in the soil;

b) at least one characteristic data of the soil compaction is determined from at least one of the radar images obtained at the end of the ramming cycles.
